Simplify / change shape measurements activities

[tischi]

There are currently two activities and it was not clear to me what the difference was. Maybe we could remove one of them?

I think the second is simply there because it was a former exercise...so probably we can remove it.

Then we could have two activities one for 2-D image and one for a 3-D image.

And it is important to have the scaling / non-scaling issue (more) obvious.

For the python activity getting a table as an output is important (including the saving as a table, could be nice).

In fact, instead of all the complicated accession of the measurements via the regionprops API we could also only do this using pandas.

As far as I have seen activity one is a bit repetitive. Maybe this should be done only with one image - once without spacing, once with spacing.

The second activity adds overlaying object features as colors, which I find a nice application, which could be added to the first one.

After discussion I think we converged to

• having only a single activity with a single image
• introducing pandas for access to feature values
• add saving the feature table as csv
• mention that in 3D some features might not be available

This is now done for the first activity.
